Cross-market report for ONE event. Give any marketplace's event URL: TicketsData finds the same event on the other marketplaces, fetches all of them live, and returns matched URLs, normalized listings per marketplace, per-market price and fee summaries, the cheapest all-in entry point and per-section price spreads between marketplaces. Returns the complete TicketsData API response, unchanged: always as a link to a JSON file, and also inline (the report's analytics in full, listings cut to the first part when large). The report also contains each matched marketplace's own full listings response, so there is no need to call get_event_listings for those marketplaces afterwards. EXPENSIVE: costs 1 report plus up to 12 API credits and takes 20 to 60 seconds. Needs a Pro plan or above. Only one can run at a time per account. Use get_event_listings instead when the user asks about a single marketplace.
